Switched to a torque wrench with a clicker after snapping bolts on 3 straight jobs

I used to just go by feel with a breaker bar on injector hold-down bolts, but after snapping two in a row on a Cummins ISX last month, I finally grabbed a $60 click-style torque wrench from Napa. Now I set it to 89 ft-lbs every time and haven't cracked a single bolt since. Anyone else ditch the old school method after it cost them a headache like that?

Read something the other day about some guys swearing by those digital torque adapters instead of clickers. Said the clickers can drift out of calibration if you drop 'em or leave 'em set too long. I still use my Napa one though, just reset it to zero when I'm done. Had a buddy snap a bolt on a Cat C15 head because his clicker didn't click when it should have. Made me paranoid enough to check mine against a beam style every few months now.

I dropped my Snap-on clicker once and it was off by 12 ft-lbs after.
